DUBAI, July 2 (Reuters) - An oil price slump hit Saudi stocks, the Gulf’s best performing market this year, on Monday while the Dubai exchange gave up its early gains due to renewed selling of property stocks.

Oil prices fell following comments from the White House that the leader of Saudi Arabia promised President Donald Trump that he can raise oil production if needed.

Contractor Drake & Scull continued to weigh on the market, falling almost 9.9 percent, bringing its year-to-date losses to more than 70 percent.

The stock has been hit by concerns about its business outlook, constant rumours on whether some of its top shareholders are committed to the stock and ongoing investigations against its previous management.

In Abu Dhabi, First Abu Dhabi Bank dropped 2 percent and Eshraq Properties slumped 9.4 percent as investors took profit after the stock’s jump a day earlier.

The gains came after the firm had said it was seeking to deploy “excess liquidity” in investments across the United Arab Emirates, after dropping merger plans with Abu Dhabi developer Reem Investments.

Abu Dhabi’s index closed almost 1 percent lower.

The Qatar index recovered from early losses to end 0.3 percent higher, helped by a 0.9 percent gain in Industries Qatar which rose 0.9 percent.
